Lagrange configurator (beta)

This web application allows you to configure analyses that reconstruct
geographic range evolution (ancestral areas, rates of disersal/range
expansion and local extinction/range contraction) on phylogenetic
trees using the
program Lagrange.

IMPORTANT BUG FIX: previous versions caused rates of dispersal and
local extinction to be incorrectly estimated when time slices were
used. The errors introduced were not large and are not likely to
have significantly affected ancestral range estimates, but
re-analysis is recommended nonetheless. Many thanks to Juliana
Chacon and Susanne Renner for alerting me of this
bug. More info...
